Overview

The histopathology of teratoma depends on the histological subtype.Teratoma is a germ cell tumor due to abnormal development of pluripotent cells.

Immature teratoma
 

Pathogenesis

  • Mature teratoma arises from a pathological transformation of primordial germ cell during the develompment.[1][2]
  • Mature teratoma comes from a single germ cell tumor after first phase of meiosis and failure of meiosis type II.[3][4]
  • Mature teratoma contains a well differentiated tumor with all three germ layers (ectoderm, mesoderm and endoderm).[2]
  • Mature teratoma may be located in the embryonic fusion midline or paraxial, mediastinum, ovary, retroperitoneum, and sacrococcygeal.[5]
  • Immature teratoma may be due to the malignant tranformation of primitive germ cell layers

Genetics

Genes involved in the pathogenesis of teratoma include:[6]

  • Gain of part or all chromosomes
    • 1p
    • 16p
    • 19
    • 22q

Associated conditions

Conditions associated with teratoma included:

Gross and microscopy pathology

The gross and microscopy features of teratoma are described below:[10][11][12]
